Zone unlocks and Heroic progression

How do I unlock the next map?

Defeat the boss named on the locked zone's picker entry with the class you want to progress. The checked lock message identifies the required boss, previous zone and class. The success message opens the destination to heroes of that class.

1. Select the hero you intend to use, then open the zone picker.
2. Select the locked destination and read its boss-and-zone requirement.
3. Complete that requirement using the selected class.
4. Return to the picker and check the newly available destination before changing class.

A Hunter's opened maps do not establish a Priest's access. Conversely, the client describes these unlocks by class, rather than limiting them to the single named hero who earned them. A familiar map appearing locked after a class change can therefore be a progression difference, not a lost save.

The zone directory lists locations and settings. Its display order is not a verified table of unlock requirements; use the actual lock message for your next step.

Which maps are in this snapshot?

The checked 0.125.0 client names 12 locations:

This is a catalogue, not an announcement of which map was added last. If an older guide lists only nine, compare its version with the one shown by your original game client. An announced map, a map included in your installed version, and a map unlocked for your class are three different things.

Normal, Heroic and gear stars are separate

More columns → Swipe, or focus the table and use the arrow keys.

For example, a Warrior clear of Heroic I opens the next level for your other classes, but a Priest still needs its own Normal clear for initial Heroic access. That Warrior clear does not give Priest equipment a one-star ceiling. Check the Priest's Armory requirements separately.

Opening a star ceiling also does not perform the upgrade. The Armory shows the piece, its allowed stars and its marks cost. Use the items and equipment guide to distinguish permanent class gear from jewelry offered during a run.

What changes on Heroic?

The difficulty description promises more marks, boss loot and talent experience alongside harder enemies. The picker displays enemy-health, enemy-damage and reward multipliers for the selected level. Read those values instead of assuming every Heroic level has the same reward increase.

Modifiers can also change which problem your build needs to solve. The checked descriptions include:

Check the selected difficulty and displayed affixes each time. This reference does not assign these modifiers to unverified Heroic tiers or supply an unverified boss schedule.

What is shared in co-op?

A lobby does not bypass a player's own class requirements. Every participant needs the selected zone and difficulty open with their chosen class. The client explicitly warns that heroes shown in red stay behind when the host enters.

The host chooses the destination; guests use the hero selected on their own picker. Before starting, have each player check that exact class, map and difficulty. If someone is ineligible, select an accessible destination or let them change hero, then recheck the lobby.

The rule that a Heroic clear opens a difficulty across classes describes progression within the save. It is not a promise that the host transfers every unlock or gear-star ceiling to friends. After a successful party run, check the unlock and Armory messages on each participant's game. See co-op setup for lobby codes, passwords and connection errors.

Which zone should I choose next?

Harder zones give more talent experience according to the client, but that alone does not establish the fastest farm. A failed run still earns talent experience from time survived, kills and bosses. Compare experience earned and time spent over repeat attempts before choosing a farming route; a higher advertised reward is not automatically a better result for your setup.
